Abstract
The utility model relates to a new style oil ring used for sliding bearings. The oil ring adopts novel elastic shock-proof connecting structure which takes elastic column pin for positioning and spring washers and screws for fixing. The two half rings of the oil ring is shaped by drawing brass rolling circle of good mechanical property, and the section of the half ring is designed into a trapezium with an oil sump. The oil ring is characterized in for the stable rotation, big oil quantity and convenient assembly and detachment. The appearance of the oil ring creates conditions for the sliding bearing of China to change from the sliding bearing which is mainly lubricated by outer pressure with oil ring lubrication as auxiliary to the oil ring which adopts self lubrication.
Description
The utility model relates to the part of sliding contact bearing, and it is a kind of novel part that is used for sliding bearing lubricating.During sliding bearing work, the oil ring that is positioned at the bearing shell middle part rotates with a certain rotating speed under rotating shaft drives, and enters bearing shell inside with the lubricant oil of going up capacity simultaneously, guarantees the safe operation under the fully liquid Frotteurism of bearing shell bearing area.Oil ring is the vitals of sliding bearing, has been widely used in the sliding bearing of various swirl gears at present.
Existing oil ring material and structure all have significant disadvantages.Common oil ring all adopts semihard red copper row or casting brass material, and the former can not carry out cutting owing to material softer, so accuracy of manufacturing is poor, the circularity of oil ring can not guarantee, and stuck not rotation phenomenon usually takes place in easy deformation during operation, have a strong impact on the trouble free service of complete machine; The latter is because the problem on the casting technique, defective (sand holes, shrinkage cavity etc.) such as foundry goods, cause producibility to scrap, waste is serious, in addition, owing to the improper castings material that causes of casting temperature control is loose, wear no resistance, the copper powders may of wearing and tearing can be polluted whole lubricating system, enters the copper powders may meeting plucking shaft bearing shelves of bearing shell and the operation surface of bearing shell, destroy the running state of sliding bearing, serious caused tile kilning accident takes place.The linkage structure of general oil ring is: an end is riveted tightly with a rivet, the other end screw-driving.Need owing to install, must leave certain clearance between rivet and the rivet hole, so inconsistent phenomenon easily takes place in the joint of oil ring mounting or dismounting back two semi-rings, this has just destroyed the circularity of oil ring, the oil ring stuck phenomenon can take place or reduce its smoothness of operation.In addition, the sectional shape of general oil ring is a rectangle, and friction area is big, can reduce the rotating speed of oil ring and causes the band oil mass to reduce.
The purpose of this utility model provides a kind of oil ring of being made by the structure and the novel material of novelty, and it has, and friction is little, and it is little to wear and tear, not yielding, the accuracy of manufacturing height, and stability of rotation is with advantages such as oil mass is big.
The utility model is realized in the following manner.The round as a ball shaping of drawing (cold drawn) brass material of better mechanical property of novel oil ring, this material not only wear resistance is good, and not yielding, can guarantee the oil ring reliability of operation.Novel elastic cylinder finger setting, the shockproof structure that removably connects of the elasticity of spring washer and screw used adopted in two semi-ring joints of oil ring.Advantages such as this structure has accurate positioning, fastening reliable, and shock resistance is good.The sectional shape of other two semi-rings is designed to have the trapezoidal of oil storage tank, thereby has reduced rubbing surface, and the oil ring stability of rotation is obviously improved, and the band oil mass significantly increases.
Accompanying drawing 1 is the planimetric map of the utility model oil ring, and Fig. 2 is the A-A sectional view, and Fig. 3 is the B-B sectional view, and Fig. 4 is the C-C sectional view, and 1 is semi-ring among the figure, and 2 is elastic cylindrical pin, and 3 is screw, and 4 is packing ring.
Below in conjunction with accompanying drawing the utility model is further described.
The novel oil ring that the utility model provides, its two semi-rings, 1 usefulness elastic cylindrical pin, 2 location, screw 3, packing ring 4 are formed by connecting.The shockproof linkage structure of elasticity that adopt the joint is made of 2, two screws of an elastic cylinder locating stud 3, two spring washers 4.Because elastic cylindrical pin allows micro-deformation, so, when oil ring is installed, as long as remove 4 screws and any one the straight pin of two joints, and be rotating fulcrum with the straight pin at another place, just can draw back an end, it is packed between bearing shell and the rotating shaft, this mounting type not only simply but also reliable.In addition, two semi-rings of this oil ring adopt and draw the round as a ball shaping of (cold drawn) brass material, thereby it is poor to have overcome original oil ring machining accuracy, yielding, the big shortcoming of wearing and tearing, the sectional area of two semi-rings is designed to trapezoidal, and has an oil storage tank, this has just reduced rubbing surface, has increased the band oil mass.
Characteristics such as the novel oil ring that the utility model provides has overcome the shortcoming of original oil ring effectively, has stability of rotation, and the band oil mass is big, and mounting or dismounting are convenient.Appearance of the present utility model, for China's sliding bearing is that master, ring-oil are to assist to the oil ring selflubricating to change the condition of having created from adopting ambient pressure lubricated, concerning the user, can save the oil leab of a cover Lubricating-oil Station and bearing itself, thereby simplified bearing structure, had very high economic value.
Claims (2)
1, a kind of oil ring that is used for sliding bearing, it is by two semi-rings and be connected and fixed part and form, and it is characterized in that all there are an elastic cylindrical pin and two set screws and two spring washers in the joint of its two semi-rings.
2, oil ring as claimed in claim 1, two semi-rings that it is characterized in that it are by drawing the round as a ball shaping of brass material, and sectional shape is trapezoidal, and an oil storage tank is all arranged.
